An energy-saving roller kiln with low heat storage

Abstract

The invention relates to a kiln, in particular to an energy-saving roller kiln low in thermal storage. Roller hole bricks of the roller kiln are made of light aluminum silicate cellucotton. Kiln walls above the roller hole bricks comprise an upper kiln wall framework; a plurality of rows of lateral hanging brackets are arranged inside the upper kiln wall frameworks in the kiln length direction; each row of lateral hanging bracket is provided with a lateral hanging rail; high-temperature-resisting dense material boards are arranged between the lateral hanging rails. The lateral hanging brackets, the lateral hanging rails and the high-temperature-resisting dense material boards tension and fix multiple layers of refractory thermal-insulation light materials onto the upper kiln wall framework for sealing and thermal insulation. The kiln walls below the roller hole bricks comprise a lower kiln wall framework; one or more rows of lateral hanging brackets are arranged inside the lower kiln wall framework in the kiln length direction; each row of lateral hanging bracket is provided with a lateral hanging rail; high-temperature-resisting dense material boards are arranged between the lateral hanging brackets and / or between the lateral hanging brackets and the kiln bottom. The whole fire face in the energy-saving roller kiln low in thermal storage adopts thin and heavy refractory slabs to ensure the firm structure and the periphery is mainly light aluminum silicate cellucotton; thermal storage is low, the thermal insulation performance is good, and energy consumption is low.

Description

technical field [0001] The invention relates to a kiln, in particular to an energy-saving roller kiln with low heat storage. Background technique [0002] The top of the high temperature zone of the traditional roller kiln mainly has a specific gravity exceeding 0.9g / cm 3 Vault or flat ceiling structure made of high-grade refractory and thermal insulation bricks, the bottom is mainly made of concrete with a specific gravity of 0.8g / cm 3 The multi-layer refractory and thermal insulation brick structure of different temperature resistance grades, the fire-seeing surface of the kiln wall adopts refractory bricks with a thickness of at least 230mm (such as 114mm lightweight mullite bricks + 114mm lightweight low-iron and high-alumina bricks) and a variety of specific gravity. Small aluminum silicate fiberboard insulation structure with lower thermal conductivity. Since the top, wall and bottom are mainly made of conventional lightweight bricks, with a specific gravity of 0.3g / ...
